D1909: cmdutil: add a kludge to make bytes repr() the same on 2 and 3

[yuja (Yuya Nishihara)]

yuja added a comment.


  I'm thinking of adding a couple of utility functions as this sort of hack
  is unavoidable around the codebase:
  
  - `pycompat.maybebytestr(x)`
  - make `repr(bytestr)` return `repr(bytes)[1:]`
  - `pycompat.rapply(f, xs)` to recursively apply `f = maybebytestr` to dict/list items
